Excessive noise and echo can quickly turn a modern home, open-plan office, or classroom into a chaotic environment. Hard surfaces like polished concrete, timber flooring, glass, and plasterboard reflect sound waves, leading to poor acoustics and reduced speech clarity. When looking for high-performance acoustic wall treatments, Autex Acoustics offers two of the most popular solutions on the Australian market: Autex Cube™ and Autex Composition®.
While both products are engineered from 100% polyester fiber (PET) to absorb sound and reduce reverberation, they serve distinctly different structural and aesthetic purposes.
What is Autex Cube?
Autex Cube is a lightweight, semi-rigid acoustic panel engineered to absorb medium-to-high frequency sound while acting as a bold visual feature wall or ceiling element. Manufactured from compressed PET felt, Cube comes in solid 12mm and 24mm thicknesses with a smooth, solid-colour core throughout the panel.
Because Autex Cube has no fabric backing or frame, installers can cut, bevel, router, or shape the panels into geometric patterns, acoustic baffles, or custom shapes without exposing raw backing materials. With Noise Reduction Coefficient (NRC) ratings ranging from 0.45 up to 0.85 (when mounted with air gaps or backing insulation), Cube is particularly effective in noisy commercial spaces, home studios, boardrooms, and living areas where targeted sound absorption and clean architectural aesthetics are required.
What is Autex Composition?
Autex Composition is a flexible, fabric-backed acoustic wallcovering designed to transform entire walls into quiet, durable, and fully pinnable surfaces. Supplied in rolls or acoustic wall sheets (typically 10mm to 12mm thick), Composition features a soft, hook-and-loop receptive velour finish over a dense acoustic felt layer.
Designed primarily for full-wall coverage, Composition acts as an all-in-one replacement for traditional wall fabrics and noticeboards. It provides an NRC rating of roughly 0.40, making it ideal for controlling background chatter and general room reverberation. Because it is resistant to pinholes, impacts, and staining, Autex Composition is widely specified across Australian primary schools, universities, healthcare facilities, and commercial office corridors.
Autex Cube vs Autex Composition
The key differences between Autex Cube and Autex Composition lie in their structural rigidity, acoustic performance ratings, surface texture, and functional utility.
| Feature / Property | Autex Cube™ | Autex Composition® |
| Material Form | Rigid panel board (12mm / 24mm) | Flexible roll / sheet wallcovering (10–12mm) |
| Acoustic Absorption (NRC) | Higher (0.45 to 0.85+) | Standard (0.40) |
| Surface Finish | Smooth, rigid PET felt | Soft velour fabric |
| Pinnability | Decorative pinboard capability | Fully pinnable & hook-and-loop (Velcro) receptive |
| Edge Finish | Clean, self-supporting solid edges | Requires neat joining along seams |
| Primary Design Style | Geometric tiles, feature panels, cut-outs | Full wall-to-wall acoustic lining |
| Installation Method | Direct fix adhesive or mechanical fixing | Direct roll-on adhesive across full wall |
Sound Absorption Performance
Autex Cube offers higher overall sound absorption, particularly in its 24mm variant or when installed as suspended ceiling baffles or acoustic fins. Autex Composition provides steady, consistent absorption across human speech frequencies, making it perfect for reducing general room chatter rather than dampening heavy low-frequency sound.
Surface Texture & Functional Utility
Composition excels in multi-purpose utility. Its velour surface allows you to stick notes, artwork, and notices using pushpins or hook-and-loop fasteners without damaging the material. Cube, on the other hand, provides a sleeker, modern architectural look suited for high-end office fit-outs and residential feature walls.
Which Acoustic Solution Fits Your Space?
Choosing between Autex Cube and Autex Composition depends on whether your project prioritises high acoustic absorption and architectural design (Cube) or full-wall coverage and practical utility (Composition).
| Choose AUTEX CUBE if: | Choose AUTEX COMPOSITION if: |
You need high sound absorption (NRC 0.45+) | You want floor-to-ceiling coverage |
You want geometric feature walls/baffles | You need a pinnable/Velcro wall surface |
You prefer a smooth, rigid finish | You are lining a classroom or corridor |
You want custom CNC cuts or branding | You require high impact & stain resistance |
